CPT code 71048 denotes a diagnostic chest radiograph series with a minimum of four views and is used to assess cardiopulmonary conditions and adjacent thoracic structures. As a commonly ordered imaging study, it plays a central role in initial evaluation of chest pain, trauma, infection, and chronic pulmonary disease, and therefore has broad national relevance for utilization, access to imaging services, and imaging policy. Key payers included in the review are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for use of a multi-view chest radiograph, payer coverage patterns and benchmark considerations, common billing and documentation points, and implications for site-of-service choices (outpatient radiology suites, hospital imaging departments, and freestanding imaging centers). The summary highlights where guidance or policy updates commonly affect coding and reimbursement for radiology services and outlines typical components stakeholders review when evaluating claims for a chest series of this scope.
